Conservation easements are intended to last—to ensure protection of important resources, no matter people’s whims—through the decades and centuries. However, the world changes and so do understandings of how best to meet conservation objectives. A land trust must be prepared to address these changes in order to ensure that its conservation work is effective while assuring its supporters and the public that it is a reliable agent of conservation. This resources serves as both a guide to responsible decision-making and a model policy for easement amendment. (Print version of ConservationTools.org guide)
